Our newly adopted "measuring stick" for obedience:
(taken from Shepherding A Child's Heart)

The children must respond to commands...

...without challenge.
...without excuse.
...without delay.

This is a tough measuring stick, particularly for me since it requires my immediate and undivided attention many times throughout the day. (Not that my kids ever say, "No;" or whine; or act as though they never heard me in the first place!) I am glad for a good way to judge Gabriel's and Bronwyn's responses to me, though. And I do feel that we will reap a good harvest; in fact, I am already beginning to taste it!
